Assignment: 01 Course Code: 8638 Question #1: Explain relationship of Science with technology. How do you look changing role of teacher with emergence of teaching? Answer: Relationship of Science with technology: Science, technology and innovation each represent a successively larger  category of activities which are highly interdependent but distinct. Science contributes to technology in at least six ways: 1: New knowledge which serves as a direct source of ideas for new technological possibilities; 2: Source of tools and techniques for more efficient engineering design and a knowledge base for evaluation of feasibility of designs; 3: Research instrumentation, laboratory techniques and analytical methods used in research that eventually find their way  into design or industrial practices, often through intermediate disciplines; 4: Practice of research as a source for development and assimilation of new human skills and capabilities eventually useful  for technology; 5:...

01 .      Give reasons why demonstration method is teacher centered while discussion method is student centered method? Answer: Demonstration method is teacher centered A demonstration method of teaching can be formulated just like this: Demonstration = words (audio) + performance (visual information) It is based on demonstrating  skills, principles, and theory via performance, movie, slide presentation, live display etc. Such technique is often  used by teachers in training and s technical educational systems. It works perfectly well at universities, colleges,  and institutions that study crafts, biology, nature and different sciences. The method uses technique or equipment  to make a 'demonstration.' It should be planned ahead of time in order to make a better explanation of the technical  or training steps to students and help them repeat the activity. Teacher-Centered Approach to Learning Taken  to its most extreme interpretation, ...

Question 02: Elaborate ICT as instructional aids in science teaching and learning process.   Answer: ICT as a pedagogical tool for support in the teaching and learning processes is still used in different degrees and with different levels of success. In view of the various applications of ICT in other areas, it is a  wonder that ICT is not more used in teaching at tertiary level. The aim of this paper is thus to investigate the use  of ICT teaching aids in the interactions between lecturer and students at tertiary level from a student perspective.  Student perceptions and appreciation of the use of different ICT teaching aids in the i nteractions with their lecturer  were analysed. Research shows that teacher-student interaction is very much beneficial in motivating students as well as in supporting them  in their studies (Panchoo, 2010, Audet, 08: 35-36). This support has gone beyond the classroom with the advent of  Information and Communication T...

Question 03: What are pre-requisites for development of a test? What are characteristics of a good assessment? Answer: In education, the term assessment refers to the wide variety of methods or tools that educators use to evaluate, measure, and document the academic readiness, learning progress, skill acquisition, or educational needs of students. While  assessments are often equated with traditional tests-especially the standardized tests developed by testing companies and  administered to large populations of students-educators use a diverse array of assessment tools and methods to measure  everything from a four-year-old's readiness for kindergarten to a twelfth-grade student's comprehension of advanced  physics. Just as academic lessons have different functions, assessments are typically designed to measure specific elements  of learning-e.g., the level of knowledge a student already has about the concept or skill the teacher is planning to teach or  ...

Question 02: Write down a critical essay on the current syllabus of English taught in grade five. Answer: Critical Analysis of Grade 5 English Book After a first glance on the contents of the book it could be noticed that the book was divided into three parts, each part consist ten units in their respective part to further. There was a workbook, Supplementary and English reader which are  included in the one book with the name called new English Reader. It also seemed to be following a pattern in its  organization of the lessons. The first page of every unit presented the aims of the unit to the students; the a first lesson  started with a reading section and then moved on to a grammar section, the final section of lesson presented practice  materials. The second part began with a listening secti followed by grammar and practice sections. The third supplementary  part was spread over referred to a previous parts/units related to the topic and language taught in...

Question 05: Choose two newspapers which publish opposite narratives of political scenarios. Write down a short  report of how you noticed the different of opinion and what is your conclusion on this issue. Answer: Interest Groups Interest groups, nongovernmental organizations (NGOs), religious groups, and labour unions (trade unions) cultivate the  formation and spread of public opinion on issues of concern to their constituencies. These groups may be concerned with  political, economic, or ideological s şissues, and most work through the mass media as well as by word of mouth. Some of  the larger or more affluent interest groups around the world make use of advertising and publică relations. One increasingly  popular tactic is the informal poll or straw vote. In this approach, groups ask their members and supporters to "vote"-usually  by phone or via the Internet-in unsystematic "polls" of public opinion that are not carried out with proper sampling BV...

Question 04: On any of the social media that you use (Facebook, twitter or WhatsApp) make group of teachers.  Initiate a discussion regarding role of education in society. Write down a report of the discussion. Answer: Many teachers discuss about it and try to guide more and give good suggestion, some likes this way of brain storming very much and try convince to hold these types of activity more times. Today's younger generation is hooked on media. If given the choice between Tweeting or textbooks, which would students choose? Many teachers think that if they allow their students to use social media in the classroom, students will be posting status updates about how their day is going, which would only detract from educational experiences. However, social media can be a powerful educational tool that provides unique and dynamic ang learning experiences to students and teachers alike. Why Use Social Media Social learning theory says that students learn bes...

What Is Molarity? Molarity is the most commonly used measure of concentration. It is expressed as the number of moles of solute per liter of solution. For example, a 1 M solution of H2SO4 contains 1 mole of H2SO4 per liter of solution. H2SO4 dissociates into H+ and SO4- ions in water. For every mole of H2SO4 that dissociates in solution, 2 moles of H+ and 1 mole of SO4- ions are formed. This is where normality is generally used. What Is Normality? Normality is a measure of concentration that is equal to the gram equivalent weight per liter of solution. Gram equivalent weight is a measure of the reactive capacity of a molecule. The solution's role in the reaction determines the solution's normality. For acid reactions, a 1 M H2SO4 solution will have normality (N) of 2 N because 2 moles of H+ ions are present per liter of solution. For sulfide precipitation reactions, where the SO4- ion is the most significant factor, the same 1 M H2SO4 solution will have a normality of 1 N. Con...

A solution is a homogeneous mixture created by dissolving one or more solutes in a solvent. The chemical present in a smaller amount, the solute, is soluble in the solvent (the chemical present in a larger amount). Solutions with accurately known concentrations can be referred to as standard (stock) solutions. Method: The solid solute is weighed out on weighing paper or in a small container and then transferred directly to a volumetric flask (commonly called a "vol flask"). A funnel might be helpful when transferring the solid into the slim neck of the vol flask. A small quantity of solvent is then added to the vol flask and the contents are swirled gently until the substance is completely dissolved. More solvent is added until the meniscus of the liquid reaches the calibration mark on the neck of the vol flask (a process called “diluting to volume”). The vol flask is then capped and inverted several times until the contents are mixed and completely dissolved. The disadvanta...

Write types of hazards. How general laboratory safety measures help keep safe from hazards? Answer: Types of hazards: Chemical Hazards A chemistry laboratory presents the greatest combination of potential hazards. However, careful attention to techniques and the avoidance of known dangers can help to make this area as safe as any other. Biological Hazards Laboratories used for teaching biology present the teacher with a wide range of insidious hazards. Besides hazards specific to biological work, dangers can arise from the presence in the laboratory of animals, micro-organisms, and plants. Because a possible hazards often does not make itself obvious until several days after infection, biological work must be treated as a special case. Radiation Hazards Each year seems to bring more and more items of equipment into the teaching laboratory that only a short while ago were confined to research laboratories. Fire Hazards M ost books dealing with fires and fire prevention make the point t...

What do you know about the term misconception? As a science teacher how will you improve misconceptions of the science concepts? Misconception A misconception is a conclusion that's wrong because it's based on faulty thinking or facts that are wrong. Your accusation about your brother's role in that unfortunate event at your party may be based on a misconception. First appearing in the 1660s, the noun misconception comes from the prefix mis-, meaning "bad, wrong," and the word conception, meaning "act of conceiving." A misconception usually results from incorrect thinking or a flawed understanding. Because they don't know the facts, many people have a misconception about how diseases such as AIDS are transmitted. It's a common misconception that Thomas Edison invented the light bulb, when, in fact, he didn't. As a science teacher how will you improve misconceptions of the science concepts? MISCONCEPTION: Students will automatically learn...

The 5 E lesson supports inquiry-based instruction. It allows children to make discoveries and to process new skills in an engaging way. Teachers can also adequately plan power objectives more effectively by using the 5E process. Children are not just learning with this method, they are more knowledgeable about their own metacognition because they are coached along and not dictated by teachers merely lecturing. The role of the teacher is to facilitate and support students as they use prior knowledge to build new knowledge. The 5 Es are:  Engage  Explore  Explain  Elaborate  Evaluate DETAILED LESSON PLAN IN SCIENCE VI OBJECTIVES At the end of the lesson, the pupils are expected to: a) Identify the effects of human activities and the cycles in an ecosystem. b) Illustrate the cycle in an ecosystem c) Give importance to the ecosystem LEARNING CONTENT TOPIC: Human Activities and the Cycles in an Ecosystem MATERIALS: Charts, Pictures REFERENCE: Science and Health 6, pp.84-87 PRESENTATI...
